Roethlisberger's optimism wasn't limited to the defense. He also offered high praise for the offensive line and second-year wide receiver Justin Brown, who had a "great" minicamp.

"I like where we are," Roethlisberger said. "I really do. I know we are young, but I have a really good feeling about this. If we can stay healthy, I like where we are and I'm really happy with our O-line and they have a chance to be great and as good as they are is going to help us."

Big Ben has a good reason to be excited about his annually beleaguered pass blockers. After Kelvin Beachum solidified left tackle and coordinator Todd Haley went to a heavy no-huddle attack, Roethlisberger was sacked just 11 times over the final eight games.

The Steelers' 6-2 record was tied for the AFC's best in the second half of last season. They will be even better this year.
